And the support team also told me :
After discussion with our specialists, one of the reasons that the changes made in the .htaccess do not affect the php, would come from the fact that we do not configure php as a module with Apache mod_php but as a server FastCGI with php-fpm. I would like to refer you to this article for more details about the differences between the two types of installation: https://buzut.net/configuration-dun-serveur-linux-php/
The headers I would like are :
Header always append X-Frame-Options SAMEORIGIN
Header set X-XSS-Protection “1; mode=block”
Header set X-Content-Type-Options nosniff
